Hi.
The exponential format was used probably due to some small
numbers. For example
tst <- rbind(
c( 5.0000e+00, 6.4836e+01, 9.5412e+01, 6.7753e+02, 8.7398e+01, 436.99),
c( 2.0000e+00, 4.0747e+01, 1.0000e+02, 0.0000e+00, 1.0000e+02, 200.00),
c( 3.0000e+00, 4.5381e+01, 7.7652e+01, 2.8075e+02, 8.8152e+01, 264.46),
c( 1e-8, 1e-8, 1e-8, 1e-8, 1e-8, 1 ))
tst
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 5e+00 6.4836e+01 9.5412e+01 6.7753e+02 8.7398e+01 436.99
[2,] 2e+00 4.0747e+01 1.0000e+02 0.0000e+00 1.0000e+02 200.00
[3,] 3e+00 4.5381e+01 7.7652e+01 2.8075e+02 8.8152e+01 264.46
[4,] 1e-08 1.0000e-08 1.0000e-08 1.0000e-08 1.0000e-08 1.00
Try roudning the numbers, for example
round(tst, digits=4)
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 5 64.836 95.412 677.53 87.398 436.99
[2,] 2 40.747 100.000 0.00 100.000 200.00
[3,] 3 45.381 77.652 280.75 88.152 264.46
[4,] 0 0.000 0.000 0.00 0.000 1.00
Alternatively, options(scipen=20) forces a fixed point printing
with more digits.
options(scipen=20)
tst
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 5.00000000 64.83600000 95.41200000 677.53000000 87.39800000 436.99
[2,] 2.00000000 40.74700000 100.00000000 0.00000000 100.00000000 200.00
[3,] 3.00000000 45.38100000 77.65200000 280.75000000 88.15200000 264.46
[4,] 0.00000001 0.00000001 0.00000001 0.00000001 0.00000001 1.00
Hope this helps.
Petr Savicky.
